Providing a common interface for discovery, exploration of
metadata and querying of different types of data sources. With
MetaModel you get a uniform connector and query API for:

MetaModel isn't a data mapping framework. Instead we
emphasize abstraction of metadata and ability to add data sources at
runtime, making MetaModel great for generic data processing
applications, less so for applications modeled around a particular
domain.

The rest of the API should reveal itself through using the
DataContext! Javadocs, wiki, mailing
lists and other resources help too of course, so check them out.
